My dog is an absolute toy-destroyer! She is a 60 lb Rottweiler/Labrador mix and she will go through almost anything we buy for her. Out of dozens of animal toys, tennis balls, squeakers, the Kong she has has held up the best! She chews on it time and time again and never seems to get bored of it. Also, she hadn’t managed to puncture it or rip it apart which is more than I can say for other toys she’s had that claim to be “indestructible”. I would purchase Kong toys over and over again for her because she loves them, and we love that they’re safe and durable. Would definitely recommend!
